To all whom it may. concern:

Be it known that we, WILLIAM Vrcronv and. WI'LLIA'M J. PARSONS, both citizens of. the United. States, and residents of Montague,-in the county of Franklin and Stateof Massachusetts, have invented certain new and useful Improvements in Magazines for Automatic Machines, of which the following This invention relates to a stock rest" or magazine for multi-spindle machines-of the type usually known as automatic screw machmes, the rods of stock being supported at to be turned and otherwise treated and out 011' by the machine itself. I

Heretofore, so farras we are aware, it has been customary to introduce new pieces of stock to the restor magazine from the outer end thereof, thus necessitating the attendant going to the rear end of the magazine for loading. As the rods are being revolved at the time, and frequently vibratihg, they are liable to catch in his clothing. Moreover, the support for the stock is such that the whole magazine sways more or less back and forth, especially if the stock is slightly bent. so as to be. crooked.

The object of the present invention is to provide astock rest or magazine which can be loaded from the front end bywhich' we supplied with the rods of stock whereby time is saved to the attendant when loading to goto the rear space is saved because the rear end of the magazine can be close to the wall of the shop since it is not necessary to supply new rods from said rear Further objects of .the invention are to provide for'flexibility or. ability of the magazine to sway or move somewhat when crooked stockis being operated upon, and to provide other improvements which will be hereinafter explained. j

To these ends the invention consists in the constr uction and combination of parts I substantially as hereinafter described and claimed.

Of the accompanying drawings :-Figure 1 is a side elevation of so much of the multispindle machine of a well known form as is necessary to an understanding of the present invention, the said machine having our improvement attached for supporting the stock. Fig. 2' represents a section. on line v22 of Fig. 1 looking in the direction of the arrows. Fig. is an elevation similar to a portion of Fig. 2 on a lar er scale.

Fig. 4 represents the portion of. e device shown in Fig. 3 butin vertical section. "Fig. 5. is a plan view of the mechanism shown n Fig. 1 in position for operation of the machine. Fig. 6 is a similar view showing the stockrest swung aside for loadin Fig. 7 re resents a section on line"7-7 0 Fig. 3.

he same reference characters indicate the same parts in allthe figures.

The work-carrying spindles 12 of themachine which is to e supplied with stock from our improved rest or magazine are shown as havlng the general characteristics of a well known multi-spindle automatic screw machine, the frame of such mach ne 1 being indicated at 13. Secured to the frame 13 is a bracket 14 which supports a laterally extended curved platform 15, (Figs. 5 and platform having recesses 16'(Figs.

6) said in which are placed rolls 17 mount- 4and7) ed upon shafts 18, the ends of which have hearings in the platform 15. Guide ears 19 are secured to the sides of the platform 15 as by screws 20, said ears serving to guide the carriage 21 which supports. the inner or front disk of the stock restior. magazine.

. The carriage 21 has a curved foot portion 22 which is mounted to be shifted upon 'the' rolls 17 guided between the cars 19, as illus-' trated by comparing Figs. 5 and 6. The

lower face of the foot portion 22 is provided with two recesses 23," 24 (Figs. 2 and 4) eitherv one of which is adapted to receive the bolt25 which is mounted in the platform 15 and is pressed upwardly'bya spring 26, said jbolt having a knob 27 to enable it to be withdrawn. The recess 23 is preferably larger than the recess 24. At any rate, the recess .23 is sufliciently larger than the bolt 25 so parts are inthe position shown in Fig.

there may be sufiicient play or lateral movement of the front end ofthe stock rest to allow the said stock rest to vibrate if the stock in the rest or magazine is crooked.

The carriage 21 is formed with a curved Seat 28 preferably provided with antifrictional rolls 29'which may be Constructed and mounted similar to the rolls 17. A disk 30 is supported by the rolls 29 and is connected by tubes 31 with a rear disk .32, the latter being supported by a yoke 33 swiveled on the upperend of a standard 34 having a base 35 which may be secured to the floor of the machine shop. Obviously, instead of having the yoke 33 swiveled, itmay be rigidly connected with the standard 34 and the latter swiveled or pivoted in the base 35. The object of this pivotal support for the rear end of the rest or magazine is to enable theother end of the magazine to be laterally swung as shown by comparing Fi 5 and 6.

en the rest or magazine is to be loaded the bolt 25 is withdrawn from the recess or keeper 23 and the carriage 21 shifted along the plat-form 15 to the position shown in Fig. 6, the bolt 25 then entering the recess or keeper 24 so as to lock the parts in position to enable the rods of stock a to be inserted in the direction of the arrows shown in Fig. 6. It will now be seen that the stock can be introduced to the magazine from the front. end thereof, or in other words, from a position alongside of the multi-spindle machine itself, and without necessitating going to the farther or rear end of the magazine. After the rods have been introduced, the"-attendant simply withdraws the bolt 25 from the locking recess 24 and swings the magazine back to the position shown in Fig. 5, when'the bolt 25 will rengage. locking recess 23 although not so closely as to preventthe magazine from having suflicient lateral play to not interfere with the operation upon the rods if the latter should "be slightly crooked.

' The disks 30, 32 connected by the tubes.

31 roperly support the rods of stock, said dis s being, however, supported so that they are readily rotatable step-by-step to permit the stock'to follow the step-by-step rotative movement of'the spindles 12 of the operating machine. i

The ordinary magazine heretofore know sways from the floor up during the opera tion of the machme, but our improved magazine enables all of thenecessary playto be taken up by the carriage 21 shifting slightly laterally upon the platform without imparting any swaying or vibration to the machine.

We claim 1. A machine of the character described having a swinging rest or magazine for the stock to be acted upon by said machine, the end ofsaid rest nearest the machine being laterally movable, and means for supportingdsaid laterally movable end when swung asl e.

2. A-machine of the character described having a stock rest comprising a pair of disks and tubes connecting them, one of said disks having a pivotal support and the other disk having a support to permit it to be shifted laterally.

3. A machine of the character described having a swinging rest or magazine for the stock to be acted on by said machine, the end of said rest nearest the machine being laterally movable, and an elongated platform for supporting the laterally movable end.

4. .A stock rest or magazine for machines of the character described having a pivotal support for one end and an elongated platform for supporting its other end, means being provided for locking the last-mentioned end in position relatively to the machine.

5. A stock rest or magazine for machines of the character described having a pivotal support for one end and an elongated platform for support-ing its other end, means being provided for locking the last-mentioned end in position relatively to the machine, the locking means being constructed to permit lateral play of the front end of the stock rest or magazine.

6. A stock rest or magazine for a machine of the character described having a pivotal support for one end, an elongated platform for supporting its other end, and means for locking the last-mentioned-end of the rest or magazine in either one of a plurality of positions.

'7. A rotatable rest or magazine for ma chines of the character described, said rest having a plurality of stock supports, the rest as a whole having a pivotal support for one end, and a curved elongated platform for supporting its other end. I

' 8. A machine of the' character described having a laterally elongated platform supported by the frame of said machine, a carriage mounted to be shifted along said platform, a pivotal support at a distance from said platform, and a rotatable stock rest or" magazlne carried by said pivotal support and platform.

9. A machine of the character described having a laterally elongated platform sup ported by the frame of said machine, a carriage mounted to be shifted along said platform, a pivotal support at a distance from said platform, and a rotatable stock rest or magazine carried by said pivotal support and platform, means being provided for locking the rest or magazine in either one of a plurality of positions.

In testimony whereof we have aflixed our signatures, in presence of two witnesses.
